Benefits of technology

This design maintains absorbing ability, prevents kinking and twisting, and ensures comfort by allowing the absorbent article to fit closely to the wearer, with the stretchable member and intermediate sheet providing flexibility and rigidity, while enhancing fluid distribution and retention.
